It feels like there’s a lot of heat on the productivity market between Apple, Google, Microsoft.

Why Apple? Because Apple also recently at iPhone’s 2013 Event announced that iWork (Pages, Numbers, and Keynote) for iOS will be free for everyone who buy a new iPhone.

So yup, it seems everybody now is heading for this market with a free version of their productivity suite…oh expect for Microsoft because in order to use Office for iPad, you need an Office 365 subscription which cost $6.99/month (or $69.99 a year).
